Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed September 14,1905. Serial No. 278.467.

To All 1072/0727 it 711/151 concern:

Be it known that we, CARL OSCAR Somm- QUIST and (humans HENRY FETTEL, citizens of the United States, residing at Chicago, in the county of Cook and State'of Illinois, have invented certain new and useful Improvements in eighing Mechanisms; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates particularly to an automatic weighing mechanism.

()ne of the several objects in view is the provision of means for facilitating the weighing of any suitable materialas, for instance, grain. in bulk-and subsequently discharge the weighed material into a storage-compartment, from which said material is discharged at the will of the operator into a receptacle for transportation.

Another object of the invention is the provision of means for facilitating the automatic handling of material in bulk by employing a mechanism which is provided with a weighing means and a storing and packing compartment or receptacle secured contiguous to said weighing means and which is capable of receiving the material discharged from said weighing means.

Vith these and .other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of p arts, as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a fragmentary view, in side elevation, of a mechanism constructed in accordance with the present invention; and Fig. 1 is a similar view of the opposite side of the mechanism. Fig. 2 is an end view, in side elevation, of the mechanism depicted in Fig. 1. Fig. 3 is a view in side elevation of a mechanism constructed in accordance with the present invention. Fig. 4 is a top plan view of the mechanism depicted in Fig. 3, parts of the mechanism which are positioned within the casing being shown in dotted lines. Fig. 5 is a transverse sectional view of the rotatable receptacle which is positioned within the casing. Fig. 6 is a top plan view of a scale-beam.

Referring to the drawings by numerals, 1 designates the parallel supports, to which is secured by any suitable means a casing 2. The casing 2 is provided with an upper compartment 3 and a lower storage-compart ment 4. The casing 2 is provided with an inclined portion 5, which produces a hopper 6. The reduced portion 5 of the casing 2 terminates in portion 7, in which is positioned valve means 8, hereinafter described. Adischarge-chute 9 is also provided with valve means 10, hereinafter specifically described.

A hopper 11 is formed upon the top or upper portion of the casing, through which the material is supplied to the revoluble receptacle 12, journaled upon the scale-beam 13, supported upon the parallel supports or beams 1 1. The scale-beam 13 comprises a pair of parallel members 14 15, Fig. 4, each bowed outwardly for producing a bifurcated scale-beam 13, Fig. 4. A bracket 16, which 'is provided with a flat base, is supported upon the supports or beams 1. The bracket 16 is provided with parallel extensions 17. Between the parallel vertical extensions 17 is positioned a block 18, which is provided with a recess or cut-out portion 19, formed upon its upper face. Upon opposite sides of the scale-beam 13 are blades 20, which engage the notched or cut-out portion 19 of the block 18. It is to be noted that the scalebeam 13 is fulcrumed upon block 18.

The rotatable receptacle 12 is journaled upon a shaft 21, supported upon the outer ends of the parallel members 14 and 15, which are positioned within the r ceptacle 2, said shaft being positioned within the elongated slots 22, formed in the casing 2. Secured to the hub portion 23 of the rotatable member 12 are parallel disks or sides 24. Partitions 25 and 26 divide the space between the disks 24 into compartments 27 27. Secured to the disks 24 are segmental plates 28, which close a part of the compartments 27. It will be seen that the rotatable recep. tacle or bucket 12 is provided, preferably, with a plurality of compartments or pockets, within which the material is positioned which is discharged through the hopper 1 1. Upon the parallelbeams or supports 1 is abracket 29, which. is provided with a central slot of sufficient length to permit of movement of the scale beam 13 therein. The movement of the scale-beam 13 is limited by an adjustable member-as, for instance, bolt which:is carried by the upper portion of the bracket 29. A bolt 31 is carried by the lower portion of the bracket 29 and projects against a follower 31', which engages the scale-beam 13. Upon said bolt 31 is positioned a spring 32. T e bolt 31 is provided with a nut 33. By adjusting the bolt 31 the tension of the spring 32 is controlled. Said spring exerts at all times an upward pressure upon the scalebeam 13. The tension of the spring may be such as to force the outer end of the beam upward, and thereby cause the rotatable receptacle'to begin to move downward, before .the desired amount of grain has been discharged into the same, so that the valve means 34, carried by the hopper 11, will begin to close, and upon the discharge of the desired amount of grain into said receptacle said valve means 34 will be entirely closed through not only the action of the spring 32,

- but the weight of the load in the receptacle.

An adjustable weight 35 is carried by the scale-beam 13.

The valve means 34 comprises slidable valve members 35, which are positioned within opposite sides of the hopper 11. Within the hop er 11 are journaled rolls 36, upon which t e valve members 35 slide. Upon each side of the casing 2 and positioned upon the supports or beams l are angular brackets 37. Upon each of the brackets 37 there are positioned auxiliary brackets 38, which comprise a base portion provided with parallel extensions. Between the parallel extensions of the auxiliary brackets, which are supported by the primary brackets 37, elbow-levers 39 are pivotally mounted. In the upper end of each of the elbow-levers 39 there are formed elongated slots 40, within which lateral projections 41 of the valve member 35 are positioned. When movement is imparted to the elbow-levers 39 for causing adjustment of the valve members 35, the extensions 41 will move longitudinally of the upper portion of the elbow-levers 39 within the elongated slots 40. Each pair of elbow-levers 39 is pivotally connected by means of an intermediate member -42, which is provided with a downward extension 43. The-extension 43 of the member 42 carries a threaded rod 44. Secured to the shaft 21 is a threaded rod 45. The rods 44 and 45 are adjustably connected by means of turnbuckles 36. By revolving theturnbuckles 36 upon the threaded rods the valve members 35 can be adjusted through the medium of the elbow-levers 39 and the intermediate connecting members 42. As the rotatable member is carried by the scale-beam 13 and as the crankarms are carried upon a stationary support-to wit, the angular brackets 37 and the beams 1when the rotatable member moves downward in 'a vertical plane the elbow-levers 39 through the medium of the means which connects the same to the shaft 21 will cause the valve members 35 to move together to close the bottom of the hopper 11, and thereby prevent the discharge of material into the'revoluble receptacle or bucket 12, positioned within the compartment 3 of the casing 2.

A shaft 47 is journaled within the chute portion 7 of the casing 2, leading to the stor. ing and packing compartment 4. Blades or members 48 and 49 are fixedly secured to the shaft 47 within the chute portion 7, said members 48 and 49 constituting the valve means 8 for closing the lower opening of the hopper 6. A shaft 50 is journaled in the chute portion 9,. to which is secured blades or members 51 and 52, constituting the valve means 10 for closing the bottom of the stor ing and packing compartment 4. It is to be noted that the blades or members 48, 49, 51, and 52 are secured to their respective shafts 47 and 50, preferably on diametrically opposite parts. The blades or members 48 and 49 are adapted to engage a packing or member 53, which constitutes a valve-seat. The blades 51 and 52 are also adapted to engage a removable member or packing 53, which constitutes a valve-seat therefor. Fixedly secured to one end of the shaft 50 is a lever 54, constituting a handle. Upon the opposite end of the shaft 50 is fixedly secured a lever 55 by means of the bolt 56. Fixedly secured to one end of the shaft 47 is a lever 57, which is of similar structure as lever 55 and is also adjustably secured to the shaft 47 similar to lever 55. The ends of the levers 55 and 57 are adjustably connected by means of threaded rods 58 and 59 and turnbuckles 60. When the lever 54, constituting a handle, is in the position shown in Fig. 1, the lower valve means 10 will be closed and the upper valve means positioned within the chute portion 7 will be opened. Upon swinging the lever 54 to the position shown in dotted lines, Fig. 1, the lower valvemeans will be opened and the upper valve means closed. The movement of the valves is ens tirely optional with the operator of the mechanism.

A locking device for preventing rotary movement of the rotatable receptacle or bucket 12 is employed, which coacts with the upper and lower valve means 8 and 10, respectively. This locking device comprises a notched or recessed plate 61, secured upon one of the beams or supports 1. Slidably secured to the same beam 1 is a plunger or bolt 62, whichis adapted to be normallypositioned upon one side of the receptacle contiguous A to the plate 61. The plunger or lockingbolt 62 is connected by adjustable means to an arm 64, fixedly secured to one end of the shaft 47. This adjustable means is similar in structure to the means connecting the ends of the levers and 57that is to say, a turnbuckle is positioned upon rod and link members 66 and 67, respectively, which are pivotally connected to the plunger or locking-bolt 62 and the arm 64.

Brake means is employed for retarding the rotary movement of the rotatable receptacle or bucket 12. This brake means comprises a curved. or angular arm 68, which is provided with an integral horizontal apertured extension 69. The removable arm 68 is pivotally secured, as at 70, to the inside of the casing 2 continguous to the side of the re ceptacle 12, which is provided with the rolls 63. NVithin the outer apertured end of the horizontal extension 69 one end of a spring 71 is secured, the opposite end of the spring being adjustably secured, through the medium of a bolt 72, to the casing 2 and one of the supports or beams 1. The tension of the spring 71 can be controlled by adjusting the bolt 72, thereby causing a greater frictional resistance to be exerted upon the rolls 63 as they come in contact with the upper surface of the curved brake-arm 68 when the receptacle 12 rotates. When the lever 54 is swung to the position shown in dotted lines, Fig. 1, the plunger or slidable bolt 62 will be withdrawn from the locking-plate 61, and if the receptacle 12 contains grain or any other material the weight of the load will cause the receptacle to rotate and one of the rolls 63 will engage the brake-arm 68 and consequently retard the movement of the receptacle 12.

The vertical movement of the receptacle or bucket controls the movement of the valve means 34, so that when a predetermined amount of material has been discharged into the receptacle or bucket 12 valve members 35 will close the hopper. It is to be noted that a partition 11 is formed centrally in the hopper 22-, so that the engaging ends of the valve members 35 are covered when said members are in their closed position.

Through the action ofthe spring 32 the receptacle 12 will begin to move downwardly before the desired amount of material has been deposited therein. Upon the exact amount of material being discharged into one compartment of the receptacle through the hopper 11 the valve means 34 will be entirely closed through the action of said spring and the weight of the load.

Vent-pipes 5 and 5 are carried by the side of the casing and communicate with the compartments 6 and 1, respectively. These pipes 5 and 5 are integral, terminating in an upper single pipe 5 The pipes 5 and 5 are employed for permitting of the passage of dust or dirt from within the compartments.

The position of the parts as shown in Fig. 1 preferably illustrates the mechanism when. the rotatable receptacle is empty. It will be noted that the valves 35 are in their open position, so that any grain deposited in the hopper will pass into one of the compartments of the rotatable receptacle. Upon withdrawing the plunger or sliding bolt 62 by actuating the lever-arm 541, which is connected to said plunger, the rotatable receptacle 12 is free to revolve within the casing 2. If one of the compartments contains material, which has preferably been placed therein through the valved hopper, the receptacle will revolve upon its axis, causing one of the rollers 63 to engage the brake-arm 68 during the rotary movement of said receptacle, and as the tension of the spring 71 upon said arm is su'flicient to nearly stop the rotary movement of the receptacle before said roller has passed off of said brake-arm it will be easy to cause the plunger 62 to move into the recess of plate 61. \Vhen the recess of said plate 61 is exactly opposite the plunger 62, the re ceptacle will be practically stationary, not only through the medium of the brake-arm, but for the fact that it is emptied when it reaches this position, as the compartment which was loaded is entirely dumped, while another empty compartment is placed beneath the valve-hopper carried by the easing 2.
